基于NTFS文件系统的保密U盘设计

Design of Secure U Disk Based on NTFS File System

U盘的安全性一直以来都是业内外关注的重点,U盘的易用性极强,特别是近年来容量大增,使得U盘成为重要的便携式存储手段。但是,U盘可读可写的特性也给病毒木马可乘之机,U盘中的资料在使用过程中容易被转移窃取。在分析U盘存储原理的基础上,提出了保密U盘设计的方案。

The security of U disc has been the focus of attention,U disk,extremely easy to use,especially in recent years the capacity increase,make U become an important means of portable storage.However,characteristics of U disk read / write to the Trojan horse virus an opportunity,U disk data in the use process is easy to transfer to steal.This paper puts forward secrecy U pad design scheme based on the analysis on the principle of U disk storage.
